It is below the course of work of independent oil cylinder multifunctional axial core described in the utility model.
Self-closing door angle be for example set be 90 while spending:
User is when opening the door, upper hinge 401 drives central axis 1 to rotate by upper hinge fixed cover 403, central axis 1 band moving axis union 12 is rotated, axle union 12 in rotary course simultaneously along the 1503 upwards axially-movables of inclined screw groove, axle union 12 movable back-up ring 10 of jack-up upwards in axially-movable upwards, movable back-up ring 10 compressive pressure springs 9 are done energy storage; When axle union 12 is rotated and make progress axially-movable, also see through universal driving shaft 13 piston rod of cushion cylinder 17 1704 and piston 1703 are rotated, draw high (referring to Fig. 3), the one way valve seeing through on piston 1703 makes the hydraulic oil in shoe cream room 1705 flow to pressurized oil pocket 1706.
When moving to spiral, universal driving shaft 13 rises as high as the banks 1504 time while spending (open angle be greater than 90 to 180), because spiral rises as high as the banks 1504 for being parallel to rise as high as the banks (vertical with the axis of spiral groove sleeve 15) of spiral groove sleeve 15 end faces, so axle union 12 and piston 1703 be not upwards axially-movable when this section of angular turn, compression spring 9 pressured states do not change, compression spring 9 keeps energy storage state constant, and hydraulic oil in shoe cream room and pressurized oil pocket does not flow mutually, so door can be parked in the optional position of 90 to 180 degree.
Independent oil cylinder multifunctional axial core described in the utility model, its mode of occupation is as follows:
User can control to adjust screw rod 3 amount of feeding (longitudinally depth location) by spiral way, the vertebra degree undergauge position of adjusting screw(rod) 3 is moved up and down, thereby change the spacing of two the second steel balls 11, thereby make movable back-up ring 10 under compression spring 9 promotes, can on central axis 1, slide up and down (referring to Fig. 1), or movable back-up ring 10 maintenance one permanent positions motionless (referring to Fig. 2,3), realizing hinge can be in automatically closed (possessing automatic door-closing function) and the conversion of freely rotating the function of (axle core can freely be opened).
The specific embodiment is:
Hinge is closed (possessing automatic door-closing function) automatically: when user rotates adjusting screw(rod) 3 in a spiral manner, make vertebra degree undergauge position move up, when vertebra degree reducing diameter part is between two the second steel balls 11, spacing between two the second steel balls 11 reduces, make size that two spacing between the second steel ball 11 can be less than necking section 107 (referring to Fig. 1, two second steel ball 11 diameters+vertebra degree undergauge position diameters are less than the diameter of necking section 107), now movable back-up ring 10 can slide up and down on central axis 1, be not subject to stopping of the second steel ball 11, therefore, under the elastic force of compression spring 9, can make movable back-up ring 10 lower surfaces and axle union 12 upper surfaces against.
Now, when hinge is closed to when being less than spiral chute 1503 and spiral and rising as high as the banks the angle of 1504 connectivity parts, own accumulation of energy compression spring 9 can move down by promotion activity back-up ring 10, movable back-up ring 10 and axle union 12 against and continue impeller-hub union 12, under the slip effect of 14 of helicla flute and sliding sleeves, axle union 12 moves down and rotates along spiral chute 1503, drives thus central axis 1 to rotate, make hinge closure automatically, realize automatic door-closing function.
Hinge can freely rotate (axle core can freely be opened): when hinge open angle is greater than spiral chute 1503 and spiral and rises as high as the banks the angle of 1504 connectivity parts, axle union 12 axially raises under spiral fluted effect, interior concave station 1206 positions of annular and the steel ball hole 109 of axle union 12 upper ends are maintained an equal level (referring to Fig. 2, 3), rotate in a spiral manner adjusting screw(rod) 3, make vertebra degree undergauge position move down, in the time of under vertebra degree reducing diameter part is positioned at two the second steel balls 11, spacing between two the second steel balls 11 increases, make two spacing between the second steel ball 11 can be greater than the size of necking section 107, now, the part of the second steel ball 11 is exposed to outside steel ball hole 109, as previously mentioned, movable back-up ring 10 is sleeved on central axis 1, in the time of outside the part of the second steel ball 11 is exposed to steel ball hole 109, the maximum spacing between two the second steel balls 11 has been greater than the interior diameter of movable back-up ring 10, makes movable back-up ring 10 be stopped and can not move down by the second steel ball 11.
Now, when hinge is closed to when being less than spiral chute 1503 and spiral and rising as high as the banks the angle of 1504 connectivity parts, own accumulation of energy compression spring 9 can move down by promotion activity back-up ring 10, but can only be resisted against on the second steel ball 11, movable back-up ring 10 can not with axle union 12 against and continue impeller-hub union 12, because axle union 12 does not have downward pressure, so axle core can freely be opened, hinge is in free rotary state.
The content not being described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
